Question: What do police officers look for when searching for drunk drivers on the highways?
ANSWER:
The following is a list of symptoms in descending order of probability that the person observed is driving while intoxicated. The list is based upon research conducted by the National Highway Traffic Administration:
Turning With a Wide Radius
Straddling Center of Lane Marker.
"Appearing to be Drunk"
Almost Striking Object or Vehicle
Weaving
Driving on Other Than Designated Highway
Swerving
Speed More Than 10 mph Below Limit
Stopping Without Cause in Traffic Lane
Following Too Closely
Drifting
Tires on Center or Lane Marker
Braking Erratically
Driving into Opposing or Crossing Traffic
Signalling Inconsistent with Driving Actions
Slow Response to Traffic Signals
Stopping Inappropriately (Other Than in Lane)
Turning Abruptly or Illegally
Accelerating or Decelerating Rapidly
Headlights Off
Speeding, incidentally, is not a symptom of DUI; because of quicker judgment and reflexes, it may indicate sobriety.
